Background/Aim. Kidney tumors account for 2-3% of all tumors. Renal cell carcinoma (RCC) is the tenth most common malignancy. Sunitinib is used as the first treatment line in patients with a good and intermediate prognosis. The aim of this study was to analyze the risk factors, frequency, and adverse drug reactions (ADRs) of sunitinib in patients with metastatic RCC. Methods. The retrospective study included 170 patients treated at the Clinic for Oncology of the Clini-cal Center of Montenegro, Urology Clinic of the Clinical Center of Serbia, and Clinic for Oncology of the Clinical Center Niš. As a data source, we used patient medical histo-ries and/or electronic patient records. ADRs were charac-terized by using Rawlins and Thompson classification. Each ADRs severity was assessed in accordance with the World Health Organization criteria. Causality was assessed using the Naranjo probability scale. Results. ADRs of sunitinib occurred in 152 (89.4%) patients. ADRs were 89% type A and 11% type C. Disorders of the blood and lymphatic sys-tem, gastrointestinal disorders, and disorders of the skin and subcutaneous tissue were the most common manifestations of ADRs of sunitinib. Causality assessment was most commonly classified as certain (60%). Serious ADRs occurred in 4.5% of patients. Most patients recovered without consequences. The most common manifestations of ADRs were: leukopenia, hypothyroidism, thrombocytopenia, diarrhea, stomatitis, asthenia, and hypertension. All ADRs were ex-pected. The number of concomitant medications and the dura-tion of therapy proved to be the most significant risk factors for ADR to sunitinib. Conclusion. Our study shows that the incidence of ADRs of sunitinib in patients with kidney can-cer is high. The ADRs were mostly moderate and mild in intensity and occurred as a consequence of the pharmaco-logical action of the drug. It is necessary to conduct contin-uous education of medical oncologists in the field of moni-toring safe drug use, as well as patients on sunitinib therapy, in order to improve their awareness of the sunitinib ADRs and the risk factors that lead to them, with the aim of reduc-ing their frequency. © 2021 Inst.

Background: Penile cancer (PC) is a highly aggressive disease, with a significant tendency for lymphatic spreading and subsequent development of distant metastases. The mutilating nature of PC surgical treatment has profound implications on the patient’s body integrity and self-image, sexual life and intimacy, voiding and mental health. The aim of our study was to comprehensively evaluate PC patients’ post-treatment quality of life (QoL), sexual activity, self-esteem, fatigue and fear of disease recurrence. (2) Methods: A cross-sectional study was conducted at the Clinic of Urology, University Clinical Centre of Serbia, and included 31 PC patients. Data were collected by means of a questionnaire. (3) Results: The average score on the Global health status scale was 67.2 out of 100 (ranging from 16.7 to 100), and the SD was 22.5. Hierarchical linear regression analysis showed that demographic characteristics, Hospital Anxiety and Depression scale (HADS) anxiety and depression scores, total Multidimensional Fatigue Inventory, Fear of cancer recurrence and Rosenberg scores and erectile function score explained a total of 78.2% of the variance in the global health status/QoL scale of PC patients. (4) Conclusions: Efforts should be made not only to increase the survival of PC patients after surgical treatment but also to enable the best possible level of QoL in the post-operative period. © 2023 by the authors.

Background/Aim. Benign prostatic hyperplasia (BPH) is a pathological process, which is one of the most common causes of so-called lower urinary tract symptoms (LUTS). LUTS affect many aspects of daily activities and almost all domains of health-related quality of life (HRQoL). The objective of this study was to evaluate the effects of operative treatment of BPH using standard clinical diagnostic procedures and effects on LUTS using the symptom-score validated to Serbian language as well as implications on HRQoL. Methods. Seventy-four patients underwent surgical treatment for BPH. The study protocol included objective and subjective parameters of the following sets of variables measured before and after the surgery: voiding and incontinence symptoms were measured using the International Continence Society male Short Form (ICS male SF) questionnaire, HRQoL was measured using the SF-36 questionnaire along with standard clinical measurement of residual urine and urine flow. Results. After the surgery, all patients had decrease of voiding scores (13.5 ± 3.3 before and 1.5 ± 1.4 after surgery) and incontinence symptoms (5.7 ± 3.9 before and 0.6 ± 0.8 after surgery) in comparison to period before operative treatment. Significant improvements in all dimensions of HRQoL were noticed, particularly in emotional health. Although mental and physical total scores were significantly better than prior to the surgery, the level of improvement of voiding and incontinence scores were significantly correlated only with the level of improvement of mental score. Conclusion. After BPH surgery, patients are likely to have normal voiding symptoms, barely some involuntary control over urination and overll better HRQoL, particularly in emotional domain. © 2019 Inst.

Introduction: The oxidative stress contributes to all three phases of carcinogenesis and represents a concomitant condition in renal cell carcinoma (RCC). RCC is the most common type of neoplasm of the kidney, and despite numerous studies the set of predictive and prognostic markers of survival are still unknown. The aim of our study was to examine the relation between antioxidant (AO) status and overall survival (OS) in RCC patients. Material and methods: Our study included 95 patients with RCC, who underwent radical nephrectomy. We analysed the prognostic role of antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase, glutathione S-transferase, glutathione reductase, glutathione, and malondialdehyde) and other clinicopathological factors (size, grade, stage, and histological subtype) on the OS of RCC patients. Results: The 5-year OS was 54.6%. The survival analysis related to AO parameters showed no significant difference in survival of RCC patients. The concentration of malondialdehyde, an indicator of lipid peroxidation, also had no significant effect on the survival rate of RCC patients. Univariate and multivariate analysis confirmed the significance of clinicopathological parameters (size, p < 0.001; Fuhrman grade, p = 0.001, and stage, p < 0.001) for patients' survival. Conclusions: In our cohort of patients, different antioxidant parameters were not found to be predictors for OS of patients with RCC, who underwent radical nephrectomy. © 2019 Termedia & Banach.

Introduction: Vesicovaginal fistulas (WF) are the most common and the most frequent type of urogenital fistulas. They may have a different etiology. In most cases, surgery is required for treatment. Objective: The aim of the study was to analyze the results of surgical therapy of WF in a tertiary level institution over the last decade. Methods: The retrospective study of results was conducted involving a total number of 99 women who were surgically treated for WF at the Clinic of Urology of the Clinical Center of Serbia in Belgrade in the period from 2001-2010. Results: Over the past ten years WF occurred after hysterectomy in 74.7% of cases, and almost twice more frequently after hysterectomy for a benign gynecological disease. In the surgical treatment of primary WF transvesical approach was used in 53.53% (52/99) of cases. Relapses were treated surgically using transperitoneal approach in all cases. No significant difference was found in respect to the applied approach in the surgical treatment of primary fistulas. In even 94% (93/99) of cases the problem of WF was solved by a single surgical intervention only. In total, in 107 interventions 8 (7.4%) relapses were recorded. Conclusion: The study showed that WF occurred after hysterectomy in three quarters of cases, more frequently after hysterectomy due to a benign gynecological disease. Early detection with timely and appropriate treatment of gynecological diseases will reduce the number of conditions that may lead to WF. Surgical treatment of WF yielded satisfactory results; it was shown that even in 94% of cases the problem of WF was solved by a single surgical intervention only, however further improvement is certainly necessary.
